Video content above is prompted by the following:
Mechanism of action also differs in the Janus kinase (JAK) inhibitor class. Tofacitinib inhibits JAK1/JAK2/JAK3, baricitinib inhibits JAK1/JAK2, and upadacitinib inhibits JAK1. Can you describe how more specific selectivity of JAK inhibition influences dose-related toxicity?
